In the new season, there appears to be a priest asking Dave and Maddy to find a woman who may turn things around. It seems that this woman became a fan of her while confessing and the last thing she revealed was her intention to kill herself. At these moments, Maddy acquires a path while David appears as he must return to New York to attend the funeral of his ex-brother-in-law.
It depicts a TV series following its natural path... while also rejecting that path, trying to keep the story alive while Willis' and Shepherd's diminishing presence desiccates the show.
